A car speeds up from 15 m/s to 30 m/s in 12 seconds. What is the acceleration of the car?

Respuesta :

1.25 m/s would be the final answer after doing a kinematic equation.

Answer:

The acceleration of the car is 1.25 m/s².

Explanation:

Given that,

Initial velocity = 15 m/s

Final velocity= 30 m/s

Time t = 12 sec

We need to calculate the acceleration of the car

Using equation of motion

[tex]v = u+at[/tex]

[tex]a =\dfrac{v-u}{t}[/tex]

Where, v = final velocity

u - initial velocity

t = time

Put the value in the equation

[tex]a =\dfrac{30-15}{12}[/tex]

[tex]a=\dfrac{15}{12}[/tex]

[tex]a =1.25\ m/s^2[/tex]

Hence, The acceleration of the car is 1.25 m/s².
